Abstract
A cycloolefin-based copolymer and a hydrogenation process are disclosed, wherein the cycloolefin-based copolymer is prepared by using: a monomer which can be easily and economically obtained by hydrogenating dicyclopentadiene that occupies much of C5 fractions from naphtha cracking; or a monomer which can be obtained by chemically bonding three molecules of cyclopentadiene via Diels-Alder reactions and then hydrogenating the cyclopentadiene. The copolymer can be used in various fields as an amorphous transparent resin.
